Abstract: A method for UE capability reduction on a per-component-carrier or a per-frequency-range basis is proposed. In NR networks, UE may be operating in multiple frequency ranges (FRs) and configured with multiple component carriers (CCs) under carrier aggregation. UE can detect an overheating problem due to the RF activity supporting high bandwidth or high MIMO rank on a specific FR or a specific CC. Accordingly, UE indicates to the network a preference for a capability reduction on the specific FR or the specific CC, e. g., a reduced number of carriers, a reduced maximum bandwidth, or a reduced MIMO rank. Such per-FR or per-CC request allows UE to restrict or reduce its capability in a manner that is specific to certain component carriers and/or certain frequency ranges rather than to a global capability reduction that affects all carriers/frequencies.

Filed: 2020-01-29
Abstract: Described is a controller for an AC to DC or a DC to AC multi-phase power converter of a type having N power converter phases, where N is greater or equal to 2. The controller comprises a control module configured to change or vary a phase shift angle of the input current or output current for each of the N power converter phases such that an average phase shift value for each of said N power converter phases over a control module AC line cycle is about, near or substantially the same value. In an embodiment of an AC/DC or a DC/AC multi-phase power converter of a type having N power converter phases arranged in parallel, an advantage of arranging the average phase shift value for each power converter phase to be substantially equal or about equal over an AC line cycle is that it reduces or eliminates any imbalances in the input currents or output currents of the N power converter phases. In preferred arrangements, the control module varies the phase shift angle of the input current or the output current for each of the N power converter phases over each AC line cycle using respective PWM switch control signals.
